We studied shock-darkening in ordinary chondrites by observing the propagation of shock waves and melting through mixtures of metals and iron sulfides. We concluded that specific dispositions of the iron and troilite grains in mixtures exist that lead to melting of iron and explain why it is possible to find a mix of metals and iron sulfides in shock-darkened ordinary chondrites.
